LNG牵引车燃料消耗量比对试验研究

Experimental Study on Comparison of Fuel Consumption of LNG Tractor

本文首先分析了目前较为常见的天然气汽车燃料消耗量测量方法及其优缺点,在此基础上构建流量测试系统对某满载状态下的LNG半挂牵引车天然气燃料消耗量进行了比对试验。道路试验和台架试验结果对比表明,此测试系统操作简便、误差较小,具有较好的实用性。

This paper first analyzes the current common methods for measuring the fuel consumption of natural gas vehicles and their advantages and disadvantages.On this basis,a flow test system was constructed and a comparison test of natural gas fuel consumption of a LNG semi-trailer tractor under a full load condition was carried out.The comparison of road test and bench test results shows that this test system is easy to operate,has small errors,and has good practicability.
